ABSTRACT:
The invention relates to an apparatus for determining and/or monitoring the process-variable fill-level of a fill substance in a container. The apparatus of the invention is to satisfy high demands with respect to chemical resistance and/or cleanability, while permitting individual parts to be replaced. In accordance with the invention, a housing part (2) is provided, which is securable on the container. Furthermore, a conductive element (3) is provided, which, when mounted, extends into the container, and which is coupled with the housing part (2) by means of a disengageable connection (4). The disengageable connection (4) is located in the interior of the housing part (2).
